Cam Selection help...
Hi,
Im trying to decide between the comp cams 268H and XE268H, Im after a cam which does not idle roughly, Id like it to idle smooth but a very slight lope wont hurt I guess. Ive looked into the High energy 268H & now found the XE268H. Desktop dyno says the two are fairly identical up to 5500rpm, the 268H has started to tail off by then hitting peak at 5500 but the XE goes on to 6000 to hit peak power. I guess this would mean the XE wouldn’t run out of legs if I set my rev limit to 5500?
This is going in a ’71 Ford 302 with Edelbrock rpm kit.
Has anyone got experience of the XE268H or the 268H? The 268H has 0.456 intake & exhaust lift with 268 advertised duration and 218 at 0.050”.
The XE268H has 0.509 intake and 0.512 exhaust lift with 268 intake & 280 exhaust advertised duration & 224 intake & 230 exhaust duration at 0.050”.
As always any advice / help greatly appreciated.
Cheers
Andy
